A kind of active Stump-jump wheel group
Technical field
The present embodiments relate to running gear technical fields, and in particular to a kind of active Stump-jump wheel group.
Background technique
It is continuous with the running gear equipment of wheel (such as clean robot, service robot and intelligent robotic toy have)
More new development, so that running gear will work in a variety of different environment, this just needs the walking mechanism of running gear can
Various Complex landform is adapted to, however the wheel bad adaptability of many running gears, walking mechanism, when encountering small stair and cable etc.
When barrier, obstacle climbing ability is limited, needs very big driving force, and is difficult to steadily clear the jumps.Due to obstacle detouring, climb building etc.
The road surface handling capacity and obstacle detouring level of mobile platform determine its working environment to a certain extent, therefore grind to Stump-jump wheel
Study carefully with certain meaning.
Research about mobile platforms such as barrier-surpassing robot, building search and rescue robots at present, there are mainly two types of: it is caterpillar
Walking mechanism and the Climbing building device for using triangle wheel.The mobile platform of two kinds of adaptation complicated landforms has the characteristics that its respectively, carries out
The walking mechanism of belt has preferable road surface handling capacity but flexibility is poor, using the Climbing building device of triangle wheel using more
It is convenient, but can not achieve autonomous driving.
